Anything to the power 0 equals to 1
And the negative power will divided by 1 to become a positive power
So the answer is D (-z/y^7)
The equation for resolving couples will come in place

Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
<h3>
Couple moment and Cartesian vector</h3>
Couple moment:This looks at the product of the forces acting on a body( in this context a steering wheel ) by the perpendicular distance that exist amidst the forces.
Cartesian vector:this is the representation of unit vectors by i and j along the x-axis and the y-axis, respectively.
Therefore, in calculating the <em>couple</em> moment t acting on the steering wheel, the equation for resolving couples will come in place

Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.

Answer:
Step-by-step explanation:
Given that Drake wants to save $750 so that he can take a class on computer analysis for cars.
He wants to save 125 per week for 6 weeks.
.Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470.
If he wants to have 750 after 6 weeks, he has to save
$ per week
Or alternately he can save same 125 dollars so that he would have 750 $ in
3 weeks.
A: Stay with saving the original amount each week but take the class a week later than originally planned.Option B: Increase the amount of money he saves each week by $15 from his original plan.
Both are right.
c. Both options A and B will allow him to meet his goal.
Answer:
A and C
Step-by-step explanation:
It A and C because if you look to the left of the graph and look for -4 on the x- axis and 1 on the y- axis you'll see 2 lines crossing each other and those 2 lines are A and C.
